Be it known that IgADoLrH S.YKLEIN,fa citizen of the United States of America, rresidingat Cleveland, in the county of Cllyaf' hoga'an'd State of Ohio, have invented certain new and usefuly Improvements in {Refrigerators, and I. hereby declarey the ,fol-k tomakeand-usethe same. v

vlowing tobe-a full, clearand exact descrip?w tion ofthe invention, such A*as-.will enableV others'skilledv in the art to which it pertains This invention relates to improvements in refrigerators, and'pertains moreV especially to ya portable refrigerator having `two pro,-

visionchambera and a metal ftankfor `re ceiving lthe f refrigerant between' said chamf bers.

The object of this inventionfisto have said tank slidable from and-to itsplace within the refrigerator and supported Vby simple,

suitable andeliicient meansfro'm the top of i the refrigerator. n

' With this object-iin view, this invention consists ofcertain features ofy construction Vand combination and arrangement of parts,

hereinafter described, :pointed out in thev claim, and'illustrated inthe accompanying drawings. f e Y.

portion 4rectangular in cross'section,y and one rangement required to render the tank capable of being removed 'through said 'opening 1 instance, as crushed viceand saltfor thefpro-y yductio'n'of brine. The VtankGr has its uppery That is, the :casing of the rrefrigerator fis provided in one upright wallA thereof with` has a'k topi 8 and is provided with anon-con.-

ducting Vorinsulating closure g which closes an opening @extending laterallythrough 'la "sald wall, and kthe tank G extends between :said opening 'ak and prevents exposure of the tankv'atsaid opening to theexternal atmosn phare; The closure Y.gis rigidly fsecuredto the tank G yin any approvedmanner.

Thefcasing ofthe refrigerator is provided, i" i lnext below ythetop D and above the tank Gr,

with alsubstantially horizontally arranged section I-Iwhich extends. between the walls A and consequently`l longitudinally ofthe 1 tank. y y ing 1n any Vapproved manner.

Two substantially horizontally extending i andY substantially parallel bars .I yare are The section Hi is ysecured to saidcasrangedv at :and longitudinally; of opposite tiallyV horizontally arrangedV flanges; 10' f which extend longitudinally of the bars and' are arranged "over Tand spaced' somewhat from the top v8 of the tank G: which 'gis provided with two metal bars J arrangedjadjacenty the top-and kat opposite'sides respectivelyof the tank.` The bars J are substantially yparallelwwith the bars I and "conse-v quently extendlongitudinally yofthe tank G. 100

The bars are provided with laterallyrand i inwardly proj ectingV 'substantially' horizoni tally arranged iianges l12 extending longitua yI dinally ofsaidv barsand Vresting on the ing. @andthe closure `gcarried by saidtank` is provided'v at the outerV side of its upper" I t langeslO Aof the barsyljlt will be observed` j that bar stJfareshiftable endwise of the bars I, and that the tank Gissecured to the barsfJ in any `approved manner and consequently said tank is suspended fromY the bars I insuch amanner as to` render said tank freelto-be shifted endwise'throughV the'open-r portiontwith apullorhandle 13.

The tankvG is provided in the closure g with` a charging aperture 14' closed t by la removable lidK.` Upony removing' the S vlidK access ishad to the interior-ott the'tank which is. charged Y 2o said aperture. x-

The tank G is providedadjacentthe lower i. extremity'of itsend` which Yis adjacent'ft'o the closure 'g with an youtlet 15 and has its bottom substantially `V-shaped in cross-sec-4 tion, as shown in Fig.".1, and: sloping upwardlytfrom saidoutlet toward the opposite end :of theftank. The' closure g is provided with meanssuch, 'for instance, as a valved y""faucet L, for controlling the flow of brine f brine, `beingr used as arefrigerant, is permitor water through said outlet, but of course ted1to accumulate inthetank G; AThe faucet Lisapplied in any-approved manner and connectswith the taIikG. The joint between theinnerend of the aucetandsaid tankis of course rendered fluidi-'tight inany approved manner. j Y i Twov upright `air *passageways 16 l are arranged at opposite'sides respectively of the tank G 'between' said tank rkand the'provision-chambers That fis,y between f each side of the `tank Gand theadjacent provision-chamber is formed an upright .air-

conducting passageway 16 andfsaid side of said tankforms one'side wallof said passageway, whereas-the other sidewall of said passageway is formed by an :upright partition P which also forms the adjacent side wall of saidchamber. Said partition extends be-V y50,

tween the walls A; of the casingfof the re- Y frigerator but-'is spaced Aat kits upper and lower ends from thetop and bottom of `said casing so that the passageway l16 formed between said partition and fthetank'* isv in communication at said ends of thefpa'rltition with l"the adjacent provision-chamber. VSaidrparftition issupported from'the walls `Abut removable. upwardly andfpreferably each of i said walls is provided atvthe lower 'endfol saidv partition with ajbracketgR instrumental vin''supporting said partition, which bracket isjvsecure'd tothev respective wall inany approved manner andis provided (see Fig. 1)

Each partition P is preferably proportion with perfora- By the construction hereinbefore described it will be observed thatfair withinftheprovision-chambers, upon ascending, as its temperature rises, can pass toand over the partitions Pand into contactwith the tank Gr Aand by said Contact has its temperature lowered and thereupon descends within the air-passageways 16.y It will also 'be observed that the lower portion ofthe tank G, being substantially V-shaped in cross-section as he'reinbefore described operates to guide cold air into the lower portions of the provisionchambers.

The top wall D of the casing of my im-` proved refrigerator is provided above each provision-chamber with an opening al affordj V ing access to'said chambenwhich opening is closed by a suitably applied door or closure Q which closes said opening, and said openingd extends-fromover said chamber to and over 'the adjacent air-conductingfpassag'ej;

way 16 andconsequently over and across the top edge of the vpartition P between said passageway and said chamber. An opening d is shown in dotted lines Fig. 4, and it will be observed upon reference to Figs.A 1 and 4 that said opening has the arrangement and dimensions required to render the adjacent partition P, upon the removal of the closure` occupying said opening, removable upwardly from within the refrigerator for cleaning purposes. It is obvious that the removability of the tank G endwise through one of the upright walls'of the casing of the refrigerator and the removability of the partitions P upwardly fromv within said lhorizontally over and extending longitudinally of and spaced from the tank, and two bars arranged at and longitudinally of oppo- 1,174,256A l a `sitesideelges respectively of'and secured to' specification;r the presence tWok Wit-` Y; v
